Employment condition modifies the using patterns of screening mammography in workers insured by the Mexican government: A case–control study

Abstract

Background: Our main aim was to investigate whether the employment condition modifies the use patterns of the screening mammography in workers insured by the Mexican government (Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado, ISSSTE; medical facilities of the Mexican government). Methods: A case–control study age-matched was done in women insured by the Mexican government, aged 40–69 years, attending a general hospital (ISSSTE). All subjects were submitted to an interview and anthropometric data registry. In the interview were obtained: demographic data, of schooling, breast cancer family history, and reproductive history; besides, mammography history during the past 2 years and place of performance (in or outside of the ISSSTE). Finally, it was evaluated whether the mammography use in the ISSSTE was related to their employment condition: Active workers (cases) vs. dependents or retired workers (controls). Results: The sample was of 252 women: 126 cases and 126 controls. Cases obtained less mammograms in the ISSSTE (P = 0.03, odds ratio = 0.54, 95% confidence interval, CI 0.30–0.96), than their dependents or the retired workers. Furthermore, cases with high education (university or higher) also obtained fewer mammograms in the ISSSTE (P = 0.03, odds ratio = 0.26, 95% CI 0.05–0.93). Conclusions: Women active workers with higher education are obtaining less screening mammograms in the ISSSTE than their dependents or the retired workers.
